Miniature Ball Bearings In Pillow Block Housing

Micromech has introduced a range of mounted miniature ball bearings designed for use in efficient and cost-effective applications in a variety of instruments and mechanisms. The Spyraflo mounted, miniature ball bearings meet the increasing demands of design engineers for an economical and precision bearing mounting method for smaller shaft sizes. The Spyraflo product consists of stainless-steel ABEC 3 precision Japanese-made ball bearings mounted in a precision-machined, sintered aluminium pillow block housing.

They are initially offered as non-aligning types as they are designed primarily for use in more precise applications. These miniature ball bearings will be offered in both inch and metric sizes from 4mm to 10mm shaft diameters, double-shielded bearings that are pre-greased for life. The aluminium body and stainless steel, together with the double shield, give the bearings a level of corrosion resistance that makes them suitable for food and wash down applications.

When previously considering the use of miniature bearings for an assembly, one of the critical design elements was precisely how the bearings could be mounted.

Typically the mount had to be precision machined, particularly when using high-performance miniature bearings. Spyraflo bearings are claimed to eliminate this task effectively and economically. The miniature bearings are especially suitable for the medical, pharmaceutical, scientific and other precision-oriented fields as they eliminate any need for designing, manufacturing or assembling precision mounts. Simply screw the pillow blocks in place to mount.

What is Class I Division 2?

Image
A Class I Division 2 is a location: (1) In which volatile flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are handled, processed, or used, but in which the liquids, vapors, or gases will normally be confined within closed containers or closed systems from which they can escape only in case of accidental rupture or breakdown of such containers or systems or in case of abnormal operation of equipment, or (2) In which ignitable concentrations of flammable gases, flammable liquid-produced vapors, or combustible liquid-produced vapors are normally prevented by positive mechanical ventilation, and which might become hazardous through failure or abnormal operation of the ventilating equipment. Class I Division 2 Classification Class I Division 2 refers to the ANSI/ISA 12.12.01 standard. This standard was previously UL1604 until UL recommended the newer ANSI/ISA standard be used and that all hazardous location products be certified under this standa

FUSE SIZING CONSIDERATIONS FOR HIGHER EFFICIENCY MOTORS

Image
When selecting the proper fuse for short circuit protection in motor starting applications, it is important to not only ensure that the fuse will not nuisance open during motor start up times, but also that the fuse will coordinate as required with overload relays. When sizing fuses between 125% and 150% of the motor nameplate current, several advantages, including ease of coordination with an overload device, a smaller disconnect, and increased short circuit protection from a lower fuse rating, can be achieved. However, if sizing at this level prevents the motor from starting, it may then be necessary to increase the fuse ampere rating and it then becomes important to know the NEC sizing limitations. As of June 1, 2016, the US Department of Energy has mandated that newly manufactured electric motors will need to meet NEMA Premium® efficiency standards. As motor efficiencies increase, motor locked rotor currents can also be expected to increase. In addition to this, with across-the-lin

7/8 16UN Connectors that Provide 600 Volts and 15 Amps

TURCK announces new A-Size 3 and 4-pin 7/8 16UN powerfast™ connectors that provide up to 600 Volts and 15 Amps of power. These IP67 rated connectors provide a modular wiring system designed to handle high current applications for machine power distribution, while providing resistance to vibration commonly associated with conveyors, motors and material handling applications. The cordsets are available with a tray rated, exposed run PVC flexlife ® cable, with or without STOOW rating, and 14 AWG wires that allow you to replace hard wiring with a robust, quick disconnect system that saves the time and money spent installing a conduit system. The A-Size powerfast line offers male and female, straight connectors, standard and custom lengths, and pigtails or extensions. To make the system complete, fully encapsulated mating receptacles, with 1/2”-14 NPT mounting threads are available.
